The bulk of UK maize and wholecrop cereal crops are fed to livestock.  MGA nutrition information aims to make the most of this feed in the production of high quality milk and meat at a low cost.  MGA Nutritionist advice is free to members.

European maize meeting report

Thursday, November 1, 2018

In early September John Morgan and Simon Draper attended the European Maize Meeting (EMM), this year held in Belgium, on behalf of the MGA.  The meeting, hosted jointly by the Belgian maize  organisations, Uclouvain and CIPF, was held in Gembloux, approximately 50 km south east of Brussels and as in the past consisted of three elements.

 A classroom-based session when the Status of the Maize Crop in different countries was outlined by our hosts.

 This year’s chosen subject was Undersowing and the Impact of Undersowing on Nutrient and Soil retention.

Moving silage

Thursday, November 1, 2018


In his latest Technical Note for MGA members, Mike Wilkinson outlines procedures for moving silage from one place to another prior to use.  Mike can be contacted via the MGA office.

 Silage is in short supply and may have to be moved from one site to another before use. The material may have been stored in a bunker or temporary unwalled heap (field clamp or pile) some distance from place of use because existing silo capacity was inadequate, or because insufficient silage was made on site to meet demand.

Health hazards from silage

Monday, August 20, 2018

Silage making can be a relatively uncontrolled fermentation process. The main fermentation activity in the silo is the conversion of plant sugars to acids. The reduction in pH preserves the ensiled crop from rotting during the storage period provided oxygen is excluded from the silage.

 Well-made silage is a safe feed for livestock, but things can go wrong with the fermentation.  Hazards to livestock and human health from undesirable micro-organisms in silage are discussed in the article.


Costs of production

Monday, August 20, 2018

The latest in the Costs of Forage Production series is based on average yields and quality.  Costs of production are assume contractors undertaking establishment and annual management tasks with crop nutrients being supplied by straight inorganic (bagged) fertiliser.  No feed out costs or waste are included. 


Westerwolds offer a real opportunity

Monday, August 20, 2018

The hot, dry conditions have hit/ obliterated most second and third cut silages, as well as impacting on many maize crops, to the point that many growers are currently short of grazed grass as well as being down on forage stocks for the winter.  The likely early harvest of maize this autumn and recent rain does offer some opportunities to fill the forage gaps, as do extending grazing in the autumn and hopefully next spring. 

Drought & Maize

Monday, August 6, 2018

In this special Technical Note for MGA members, Mike Wilkinson outlines prospects for the 2018 maize crop and its likely feed value.  

 This year’s weather to date in large parts of the UK has comprised a wet spring followed by drought. Many MGA members are short of feed and are taking steps to secure additional supplies for the coming winter.  A lot of hay and whole crop silage has been made. Some members are suffering from failed maize crops due to prolonged lack of soil moisture.

 What are the prospects for the maize crop this year and how might maize silage feed value differ from a normal year?

Topical Issues in Nutrition 2018

Monday, August 6, 2018

Feeding dairy cows during the last six months has continued to provide new challenges for both dairy producers and ruminant nutritionists. This article written by Chris Bartram, head of Nutrition at Mole Valley Farmers highlights several key points to consider. It also pinpoints a few areas that are likely to become more important in the future.

Friday, July 21, 2017

In his 6th Technical Note for MGA members, Mike Wilkinson looks at harvesting and silage quality.  Mike can be contacted via the MGA office.

 When to harvest?    

Changes in forage maize quality with advancing crop maturity are mainly the consequence of changes in whole-plant DM concentration. Post-fertilisation, sugars (mainly fructose polymers and glucose) are translocated from leaf via stem to rachis (cob) and finally to grain where they are polymerised into starch as the grain fills and increases in weight.  The progressive changes from sugars in solution to starch in suspension (milk) and then to solid starch is indicated by the rise in milk line from the base to the top of the grain as it matures.  This process is accompanied by significant loss of water from the plant. There is also loss of water due to leaf senescence and cell rupture due to disease and/or frost damage.
